Working Party 1 - International Road Traffic Conventions
WP1 has responsibility for the Vienna and Geneva Road Traffic Conventions•A review of how the international road traffic conventions support the use ofAdvanced Driver Assistance Systems (ADAS) and Automated Driving Functions(ADF).

•The Vienna Convention has been amended to allow for vehicle systems which
influence the way that vehicles are driven; the use of ADAS systems is recognisedby this wording.

•The Geneva convention has not been modified but synchronisation is still the goal.

•There is a consensus that testing is 'allowed' by both conventions, as long as adriver (or operator) is ready, willing and able to retake vehicle control if necessary.
4World Forum for Harmonization (WP29)
Two principle operating groups:
1. WP29 Informal Group to provide strategic
direction for automated technology.
(Intelligent Transport
Systems/Automated DrivingGroup(ITS/AD) )2. Developing the UN Regulation concerning
vehicle steering systems to permit certain
levels of autonomy.
(GRRF and the GRRF Informal Working
Group)

6WP29 Categories of Automated Function
WP29 Classifications Automated Functions
Category A Operates at a speed no greater than 10 km/h to assist the driver, on demand, in low speed or parking manoeuvring.
Category B1 Assists the driver in keeping the vehicle within the chosen lane, by influencing the lateral movement of the vehicle."
Category B2

Initiated/activated by the driver and which keeps the vehicle within its lane by influencing the lateral movement of the vehicle forextended periods without further driver command/confirmation

Category C

Initiated/activated by the driver and which can perform a single lateral manoeuver (e.g. lane change) when commanded by thedriver.

Category D

Initiated/activated by the driver and which can indicate the possibility of a single lateral manoeuvre (e.g. lane change) but performs
that function only following a confirmation by the driver.

Category E

Initiated/activated by the driver and which can continuously determine the possibility of a manoeuvre (e.g. lane change) andcomplete these manoeuvers for extended periods without further driver command/confirmation."

Terms of Reference
1. The informal group shall review the requirements and limitations associated with AutomaticallyCommanded Steering Function technology (ACSF) as defined in Regulation No. 79. It shallprepare a draft regulatory proposal regarding advances in control system technology and thetransport opportunities provided by the Vienna and Geneva Conventions.
2.

The informal group shall address the following issues:a.
Review the current speed limitation (10 km/h) with the purpose ofpermitting ACSF functionality during interurban journeys.
b.
Define Human Machine Interface (HMI) requirements for communicating
between ACSF-system and the driver (e.g. system status, malfunction,transition).
c.
Define requirements to enable the evaluation of ACSF during periodic
technical inspection.

Items of Immediate Discussion (1)• Category A and Category B1 – proposals being presented to WP29
next month for application from April 2018.
• Categories B2, C, D & E to be discussed• Does Category C introduce risk of misuse?

• Should traffic sensors be mandated or should they be prohibited?

• Can transition to driver control with a Category E system be managed in atimely and safe manner?

• Extend activity to systems of SAE level 3 and 4 capability.
• Vehicle and system-status data:• What should be stored?
• Who should have access to it?
